Memory Chip Manufacturers Outpace Magnificent Seven in 2026 with Triple-Digit Returns

The year 2026 marks a turning point in the stock markets: the Magnificent Seven – Apple, Microsoft, Amazon, Alphabet, Meta, Tesla and Nvidia – are losing their lustre. While these technology giants gained just 5.5 percent, the Morningstar US Large-Mid Cap Index rose 10.6 percent through July 13, 2026, according to Morningstar. It is the weakest performance of the group since 2022.

A clear market rotation took hold: investors sold off large tech stocks and instead bought semiconductor and memory chip manufacturers. These companies benefit directly from the expansion of AI infrastructure – and outperform the Magnificent Seven with sometimes triple-digit returns.

Why the Magnificent Seven are faltering

The underperformance of the tech giants has structural reasons. Investors are increasingly sceptical that massive capital expenditure on AI data centers and software development will pay off. Microsoft, as the weakest stock in the group with a decline of 20.4 percent through mid-July 2026, exemplifies this scepticism. According to Morningstar, investors fear that gigantic spending on building AI data centers will not generate sufficiently high returns.

Meta is also facing similar reservations. The question of how the company intends to monetise its AI investments remains unanswered. The stock reacted volatilely: on days when Meta presented convincing monetisation approaches – such as with Muse Spark 1.1 for developers – the price rose, as Morningstar analysed.

Tesla is struggling with shrinking margins. Although the automaker recorded revenue growth of 21 percent year-over-year in the first half of 2026 (through June 30) and vehicle sales rose 24 percent, profitability collapsed. Operating margin fell from 4.1 percent in the second quarter of 2025 to 1.4 percent in the following quarter – a decline of 2.7 percentage points. At the same time, research and development costs exploded 49 percent and administrative expenses surged 45 percent year-over-year. With a price-to-earnings ratio of 327, the valuation appears ambitious.

In early February 2026, each individual Magnificent Seven stock underperformed the S&P 500. By end of October 2026, only two stocks – Nvidia and Apple – beat the market, as analyses from Motley Fool and Yahoo Finance showed.

The winners: memory chip manufacturers dominate

While software giants stumble, capital is flowing into hardware companies building the physical backbone of the AI revolution. Memory chip producers lead the market with triple-digit returns.

SanDisk, a flash memory manufacturer, recorded a share price increase of 605.2 percent since the start of the year through July 13, 2026 – a performance that leaves all Magnificent Seven far behind. Micron Technology and Advanced Micro Devices also achieved significant gains, as Morningstar documented.

This shift reflects a fundamental revaluation: investors are betting on companies that deliver concrete products for the AI boom – memory chips, processors, hardware – rather than on software providers whose monetisation is still uncertain.

Is entry still worthwhile?

The question of entry depends on the specific company. For SanDisk, Micron and AMD, current valuations after massive share price increases rather call for caution. Anyone entering at current prices is buying after a multiple increase in valuations – an entry point that is historically rarely favourable.

The fundamental logic remains intact: expansion of AI infrastructure requires substantial amounts of storage and computing capacity. Semiconductor and memory chip manufacturers supply this demand directly, while software companies must first prove that their AI applications find paying customers.

With the Magnificent Seven, a differentiated picture emerges. Apple and Nvidia, the two stocks that still beat the market in October 2026, demonstrate relative strength. Microsoft, by contrast, exemplifies the challenges facing the group: high investments, unclear returns, sceptical investors.

Market observers had already predicted in mid-2026 that only two of the seven technology giants would outperform the market – an assessment that proved correct by October. According to Motley Fool, the Magnificent Seven remain more volatile than the S&P 500, both up and down.

For investors, this means: the blanket dominance of tech giants is over in 2026. Those betting on individual hardware stocks like memory chip manufacturers carry increased downside risk after strong gains. Those investing in the Magnificent Seven must reckon with continued volatility and varying prospects depending on the company. Broad diversification remains sensible – the Morningstar US Large-Mid Cap Index shows that the overall market outperformed the tech giants in 2026.
